Darboux transformations and hidden quadratic supersymmetry of the one-dimensional stationary Dirac equation
N. Debergh, A. A. Pecheritsin, B. F. Samsonov +1
A matricial Darboux operator intertwining two one-dimensional stationary Dirac Hamiltonians is constructed. This operator is such that the potential of the second Dirac Hamiltonian…

On oscillatorlike Hamiltonians and squeezing
J. Beckers, N. Debergh, F. H. Szafraniec
Generalizing a recent proposal leading to one-parameter families of Hamiltonians and to new sets of squeezed states, we construct larger classes of physically admissible Hamiltonia…
